A garden grown specifically for the purpose of testing and evaluating plants is called a trial garden. Universities, plant breeders, and garden-industry companies frequently have trial gardens, as do many private and public botanical gardens and professional garden journalists. In the classic trials model, newly developed varieties of plants are compared with the closest similar industry standard plant throughout their life cycle—from germination/propagation through maturity, from seed to harvest. By growing new varieties side-by-side with existing ones, researchers can determine whether these new varieties are indeed better, and, if so, in what respects.
